What is the best insecticides to use to eradicate fruit worm of tomato?

Answer 1

Tomato Fruitworms moths lay eggs near the stem of the green fruit and within 1 week the hatched larvae bores into the fruit where it feeds.
... Sour milk kills eggs & larvae! Just pour some on.

For long-range control, Bacillus thuringiensis (Bt) controlls worms & moths.

Chemical Control: Sevin 5% dust. Treat every 5-7 days when fruit begins to set as once inside the fruit the pesticide has little or NO effect. (1)

OR
Organic vegetable spray: In a blender mix 4 cloves of garlic with 1 chopped onion. Place this mixture in a large glass jar and add 2 cups of water. Add 2 teasp. of bottled hot pepper sauce (or grind up a hot pepper) stir ingredients together and steep for 2 days. Strain the mixture and add one Tablesp. Ivory liquid soap(or pure soap liquid).Then DILUTE with 5 cups of water. Don't forget the last part or it'll be too strong. Apply only in the cooler part of the day. (2)

Answer 2

I am a believer in organic gardening, so I have little information about pesticides.
However, I know about 'companion planting'.
For tomatoes, if they are planted along with Basil, the Basil is a natural deterrent for a lot of bugs that would otherwise plague tomatoes.
Basil is also a tasty herb to add to your cooking, so you can kill 'two bugs with one herb' :)
If you already have mature tomato plants and have not planted Basil along with them, consider making an infusion of dried Basil: Add ca. 1 oz of dried Basil to 1 Quart of very warm water. Let steep. Strain through a small sieve or cheese cloth.
Put fluid into a clean spray bottle. Spray tomato plants.
